A Change in Plans For Sass 3.3

Sass 3.3 is coming soon, and along with it several major new features. It supports source maps, SassScript maps, and the use of & in SassScript. In preparation for its release, we've put out a couple of release candidates to be sure that everything was set and ready to go. Unfortunately, it wasn't.

Release candidates often turn up small bugs and inconsistencies in new features, but it's rare that they find anything truly damning. In this case, though, several users noticed an issue with using & in SassScript that rendered a sizable chunk of our plan for that section of 3.3 unworkable. It's not a fatal issue, and we think we have a good plan for dealing with it (I'll get to that in a bit), but it is a problem.

The Background

To understand what's wrong, first you need to understand the reason we decided to make & accessible to SassScript in the first place. One thing users want to do pretty often is to add suffixes to classes. Sometimes this takes the place of nest

Project-specific lint rules with ESLint

A quick introduction

First there was JSLint, and there was much rejoicing. The odd little language called JavaScript finally had some static code analysis tooling to go with its many quirks and surprising edge cases. But people gradually became annoyed with having to lint their code according to the rules dictated by Douglas Crockford, instead of their own.

So JSLint got forked into JSHint, and there was much rejoicing. You could set it up to only complain about the things you didn't want to allow in your project, and shut up about the rest. JSHint has been the de-facto standard JavaScript linter for a long while, and continues to do so. Yet there will always be things your linter could check for you, but doesn't: your team has agreed on some convention that makes sense for them, but JSHint doesn't have an option

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

intellij javascript live templates

Just a dump of handy live templates I use with IntelliJ. They should also work with WebStorm.

How to

Go to settings.
Search for live templates.
Under the javascript section you should be able to manage your templates.

I'm having trouble understanding the benefit of require.js. Can you help me out? I imagine other developers have a similar interest.

From Require.js - Why AMD:

The AMD format comes from wanting a module format that was better than today's "write a bunch of script tags with implicit dependencies that you have to manually order"

I don't quite understand why this methodology is so bad. The difficult part is that you have to manually order dependencies. But the benefit is that you don't have an additional layer of abstraction.

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

	(function (root) {

	var type = function (o) {

	// handle null in old IE
	if (o === null) {
	return 'null';
	}

	// handle DOM elements

	.block {
	width: 80em;
	@media #{$mobile} {
	width: 100%;
	}
	}

	.foo {
	background: orange;
	@media #{$mobile} {
